Display device and apparatus

Abstract

The present invention provides a display device which can realize the positioning with high accuracy in mounting a display panel to a casing. Further, the present invention provides a display device which can simplify the mounting structure of a display panel and can mount and fix the display panel to a casing easily and with high accuracy. A pair of mounting holes are formed in both ends of a peripheral portion along one side of an OLED panel which performs an image display. By allowing fixing members to pass through the pair of mounting holes, the OLED panel per se becomes the mounting reference and is positioned with respect to the casing with high accuracy. Further, by forming notched portions on another side of the OLED panel which faces one side of the OLED panel in an opposed manner, the OLED panel is supported on a plurality of points and hence, the OLED panel is positioned and fixed with high accuracy.

1. A display device comprising:
 a display panel which includes an effective display region for performing an image display, said display panel comprising a substrate, the substrate including a thin film transistor and holes, each of the holes being bored through said substrate and arranged outside of said effective display region; 
 a casing which includes an opening window which exposes the effective display region of the display panel and accommodates the display panel in a state that the effective display region is exposed through the opening window; and 
 fixing members, each of which is allowed to pass through a corresponding hole among the holes formed in the substrate and fixedly arranges the substrate on the casing. 
 
     
     
       2. A display device according to  claim 1 , wherein said substrate comprises at least one notched portion. 
     
     
       3. A display apparatus comprising:
 an OLED panel which includes an effective display region for performing an image display; 
 said display panel comprising a substrate, the substrate including a thin film transistor, an organic EL layer and holes, the holes being bored through said substrate and arranged outside of said effective display region; 
 a casing which includes an opening window which exposes the effective display region of the substrate and accommodates the OLED panel in a state that the effective display region is exposed through the opening window; and 
 fixing members, each of which is allowed to pass through a corresponding hole among the holes formed in the substrate and fixedly arranges the substrate on the casing. 
 
     
     
       4. A display apparatus according to  claim 3 , wherein in another side of the OLED panel which faces one side of the OLED panel in an opposed manner, at least one notched portion which supports the OLED panel is formed.
